Question 94 (d)

Taking $x=\frac{-4}{9},y=\frac{5}{12}$ and $z=\frac{7}{18},$ find

Find the rational number which when multiplied by y to get x.

Answer 1

Given, $x=\frac{-4}{9},y=\frac{5}{12}andz=\frac{7}{18}$
Suppose, if A is multiplied by y then we get x.
i.e. $A\times y=x\Rightarrow A\times \frac{5}{12}=\frac{-4}{9}\Rightarrow A=\frac{-4}{9}\times \frac{12}{5}=\frac{-48}{45}$
